How chook started their logo design journey

Company name

Dig This

Overview

Dig This (http://www.20tonsoffun.com) or (digthis.info), is America's first ever heavy equipment theme park.
Established in 2007, Dig This has given hundreds of participants the pleasure of manning the controls of 20 ton excavators, bulldozers and loaders in a fun, safe adult sized sand box !
Our purpose is to simply let people play on huge Caterpillar equipment during 1 hour, half day or full day organized sessions.

Tell us a bit about who you are and the people you reach

Requirements

After reviewing the logos to date that we have received, none are on target. I am sure those of you still in the contest are getting frustrated but we need to change tact since these entries are not what we are looking for.
Remember we are looking for a logo that is unique, simple and not making us look like a construction company. Although some attempts have left out images of equipment which I think now is a good move, you need to get creative with a fun design. Take for example our current logo. There is a crushed cone in the graphic with tracks going over it. Maybe work on that approach since it is fun and simple as well as including Dig This with the cone in it.
Or if you have any other ideas like this please share.
Once again I sincerely appreciate your efforts todate and hope you can continue with this competition.
